The app allows to send GET requests to the database service. The requests are monitored by a circuit breaker that watches for errors in the requests. There are different endpoints that the GET request can be send to. These can be selected in the "Choose request type" selector.
The circuit breaker has two different types that can be configured:
The ConsecutiveBreaker opens after n requests.
The SamplingBreaker opens after a percentage of requests fails within a certain time period.

The backend listens at http://localhost:3300/request for the incoming default GET requests and automatically transfers them to the backend of the database service (usually sitting at http://localhost:3000 when running).
-
from http://localhost:3000/request-handler/balance to get the balance from the database service.
-
from http://localhost:3000/request-handler/customer-name to get the customer name from the database service
The backend listens at http://localhost:3300/config/ for a POST request containing the breaker config
The breaker config should have the following format:
breaker : string;
timeoutDuration : number;
resetDuration : number;
monitorDuration : number;
threshold : number;
minimumRequests : number;
consecutiveFailures : number;
